Doctor insights on:
Myocardial Perfusion Test
CAD: The purpose is to diagnose significant coronary artery disease (CAD). If the scan is positive for ischemic changes in the heart, then you will benefit from aggressive medical treatment, angiographic treatment, or surgery. If the scan is negative (and done properly), your risk for CAD or a significant injury such as a heart attack in the next few years is very low. ...Read moreSee 1 more doctor answer
Cardiac stress test..: A myocardial perfusion scan is used to detect ischemia or infarction (heart attack) and also to evaluation cardiac function (ejection fraction) and ventricular volumes. If there is significant ischemia sometimes a stent can be placed to prevent infarction. ...Read moreSee 1 more doctor answer
See blood flow: Myocardial perfusion studies show the pattern of blood flow (perfusion) to the tissue of the heart muscle. The radiotracer goes where the blood goes and this shows how well the tissue is nourished. It can be an indicator of blocked arteries when the perfusion pattern is abnormal. ...Read more
Stress test : This is a chemical stress test. You will be given a medication and then pet scan of your heart will be done to evaluate the blood flow in different parts of the heart. If there is any significant blockage, it will show up as a defect in the images. ...Read moreSee 2 more doctor answers
Have chest tightness in cold air or with anxiety. Ekg, blood tests, echocardio and myocardial perfusion scan (cardio) are normal. What could it be?
Stress Test: That uses a radioactive tracer to evaluate blood flow in the coronary arteries. Images are taken at peak exercise and at rest . These images are able to compare blood flow to the heart in specific territories supplied by each coronary artery and any flow disparity would be consistent with a potential blockage in that artery. ...Read more

Perfusion scans: The main risks to these studies relate to the exercise stress used and to the radiation exposure. In general both are very well controlled and the complications and negative outcomes to these studies are very few and uncommon in good labs. The commonest side effects are with Persantine and Adenosine used to simulate exercise. Regadenoson a newer agent has few side effects. ...Read more
